Furthermore, if the monosomic 1R chromosome did pair with one of the wheat chromosomes at male meiosis of the F1 hybrid, from which WER-1-1 was derived, the recombinant chromosomes, i.e., the abnormal 1R chromosome and the 1R-wheat translocation chromosome, will go into different tetraspores, and after anther culture, these two chromosomes should appear in different pollen-derived plants.
